The Black Sun crime syndicate came into being at the end of the Great Galactic War around 3600 years before the Battle of Yavin.

The syndicate's influence soon spread throughout the galaxy, and the Clone Wars allowed further expansion as the Republic's military was concentrated on the war.

By the time of the Empire, Black Sun had dealings with the Emperor, Darth Vader, and members of the Rebel Alliance and made enemies on both sides resulting in attacks which crippled the syndicate's infrastructure.

There was a brief revival starting in 24 ABY, but 19 years later the Jedis of the New Republic arrested thousands of Black Sun agents dealing the organisation a crushing blow.
